CAR-DOOR.

SPECIFICATION forming part of Letters Patent No. 411,852, dated October 1, 1889.

Application filed April 16, 1389.

To all whom it may concern.-

Be it known that 1, CHARLES EOssHARD, a citizen of theUnited States, residing at Trenton, in the county of Clinton and State of Illi nois, have invented a new and useful Car- Door, of which the following is a specification.

My invention relates to improvements in car-doors; and it consists in certain novel features hereinafterdescribed and claimed.

In the accompanying drawings, Figure 1 is a side view showing the door closed. Fig. 2 is a similar view showing the door opened.

Referring to the drawings by letter, A designates a portion of a side of a car, which may be of the usual or any preferred construction, and is provided at a proper point with the door-opening B, as shown. Adjacent to the sides of the door-opening I provide the standards or guides O 0, between which and the side of the car the door-sections D operate. These standards or guides are secured at their lower ends in the floor of the car and at their upper ends in suitable brackets E, as clearly shown, and they serve to prevent the sections falling away from the side of the car, as will be readily understood.

The door-sections D D are substantially triangular in form, and their meeting edges are arranged to overlap, as clearly shown. The sections are pivoted to the side of the car and on opposite sides of the door opening by means of suitable pivot-pins passed through their lower angles, so that they can be swung upward and to one side to uncover the dooropcning. When the sections are raised, they engage keepers F F, secured to the side of the car, so that they will be held in proper position to move readily in rear of the guides or standards 0. The sections may be pro vided with a suitable lock, and they may be made large enough to entirely cover the dooropening, or merely large enough to cover half of said opening, as may be desired.

From the foregoing description it will be seen that I have provided a very simple car- $erial No. 307,389. (No modall) door, which can be manufactured and applied to'the car at atrifling expense and which will effectually prevent the escape of grain or other articles placed therein. The standards C prevent the door-sections falling away from the side of the car under the pressure applied thereon by the contents of the car, and the overlapping construction of the meeting edges of the sections aids the standards in thus maintaining the doors in their proper position. When it is desired to open the door, each section is swung upward on its pivot, as will be understood, and this feature of my device will especially commend itself, as the labor required to lift or swing each section is considerably less than that required to open ate the sliding doors heretofore used.

In my device no fastening-bars are required, and an economy in the transportation of freight is thus effected.

Having thus described my invention, What I claim, and desire to secure by Letters Pat cut, is

l. The combination, with the car, of the triangular door-sections pivoted to the side of the same and having their adjacent edges overlapping when closed, as set forth.

2. The combination, with the car, of the standards C and keepers F, arranged on opposite sides of the door-opening in the side of the car, and the triangular door-sections pivoted on the side of the car and moving between the same and the standards C and adapted to engage the keepers F, as set forth.

A car-door consisting of two triangular sections pivoted on opposite sides of the dooropening and having their longest edges adapted to meet across the door-opening, as set forth.

In testimony that I claim the foregoing as my own I have hereto aflixcd my signature in presence of two witnesses.

CHARLES BOSSHARD.
